How do you know if you have bluetooth on your computer
A computer doesn’t actually «know» how to do anything. A computer will do exactly what it is told to do, whether it is good, bad, right or wrong. A computer never looks for the solution to a problem, it merely spits out the output of the instructions it was given..
That said, a computer is turned o…n. The bios chip activates and has instructions hard-wired into it to know the type of motherboard it has and the locations of all the motherboard chips and slots. The slots run their diagnostic tests and upon a successful test, the bios instructs the hard drive to give the processor further information and instructions to run..
The hard drive usually contains the operating system like Windows or MacOS. The processor now has full control of the system and activates all the peripheral devices and cards that were not activated by the bios, as long as the instructions for those peripherals or cards have been stored on the hard drive. Then it performs diagnostics on those peripherals, and upon success or failure will store that information in a system configuration file which keeps track of the status of these devices for other programs to reference..
For example, if you use PalTalk and Internet Explorer, both programs will want access to a sound output device. Without the system configuration file, each program would independantly have to have instructions on how to turn the sound card on, adjust the volume, and interperet the information into sound through that card. So instead of writing all that code, all the programmer has to do is give the OS a small instruction so the OS can do the rest. It’s like a waitress giving an order to the cook. The cook knows how to make a cheeseburger because he read the instructions. All the waitress has to do is say «cheeseburger» and the cook does it automatically. Without the system configuration file, the waitress would have to tell the cook step by step how to make the cheeseburger..
Password protection and encryption are where people get into a lot of trouble if they don’t understand this basic principal that computers are STUPID. Computers are like incredibly fast, strong, efficient MORONS who will do absolutely anything that anyone anyone ANYONE tells them to do. Password protection, encryption and firewalls don’t give the computer a sense of morality or loyalty. These protections are just another set of instructions. If you type in the incorrect password, a computer doesn’t tell you «No,» it is saying yes. It is actually giving you the output you requested. Your input was «squirrell34.» The computer takes your input, sees that «squirrell34» is different from «slick20» and cheerfully gives you your requested output, «Access Denied.» Even though you paid for the machine and have a God-given right to the output that you *want* the computer will always give you the output that you *requested* by way of your input filtered through the instructions..
Now here comes Darth Vader. He stumbles upon a piece of paper that says «squirrell34». Darth Vader breaks into your home and types it in. The computer sees that the input «squirrell34» is equal to «squirrell34» so it takes a look at Darth Vader, doesn’t believe him and asks for some ID, right? Nope, it gives the Imperial Lord your recipe for chocolate asparagus without a second thought..
Anyway, that’s the basic answer — computers don’t know what to do. Computers are just big collections of tiny lightswitches that turn on other tiny lightswitches when we arrange them properly..
I’m just kidding. It’s actually magic..
The computer checks for actions and/or conditions specified in its programming/code and then reacts according to what is written in its programming. An example:.
Loop Do ( This is where the computer goes back to when specified to ).
When Microsoft Word is open ( condition 1 ).
When able to type ( another condition ).
When a keyboard button is pressed ( a third, more broad condition ).
Save the pressed button in memory as a variable named «blabla».
Draw the pressed button (known as variable «blabla»)( Reaction/Action ).
Loop ( Start over from Loop Do ) (MORE)
How to Use a Bluetooth Headset With a Computer
Using a Bluetooth headset frees you up to work with your hands on your computer to search and type, while speaking with another party. In order to use a Bluetooth headset with your computer, you need to «pair» it meaning let the computer and the Bluetooth device create a connection. Devices do vary, as do operating systems, but the general rules of pairing will remain the same.
Make the Device Discoverable
Most devices have a way to pair with the computer. It is important to first put the device in discovery mode. This is where a Bluetooth signal is sent out searching for another Bluetooth signal to connect with. The closer the two devices are to each other, the easier pairing is. A Lenovo Bluetooth headset generally has a button that is used to accept or decline calls. This button should be held down for several seconds, until an LED light will begin to blink showing that the device is now discoverable. Unless the computer is not equipped for Bluetooth or has it disabled for some reason, you don’t need to make the computer discoverable. A pop-up screen appears on the computer, asking if you want to connect to the device.
Manufacturers such as Lenovo Bluetooth make a variety of devices, so be sure to read the instruction manual for the specific sequence. Once the device is paired, it should not need to be paired again, unless you remove it from the authorized devices.
Windows Bluetooth Pairing
Most laptops are already equipped for Bluetooth pairing, while desktops may not be. If your desktop is not Bluetooth enabled, you may need a USB adapter. For example, Kensington offers a small USB insert that allows keyboards, headsets and mouses to be paired with computers not capable of Bluetooth connections naturally.
These are plug-and-play USB ports that generate a pop-up window to download the Bluetooth adapter driver into the Window’s operating system. Once the driver is installed, the USB plug-in remains in the USB port and headsets such as a Lenovo Bluetooth headset will be seen in discovery mode. If you remove the USB driver you may need to repair the device after reinstalling the driver. These work with most Windows 10, 8.1, 8 and 7 operating systems.
Mac iOS Pairing
Most older Mac operating systems through Mac iOS 10 have Bluetooth capability with a variety of devices, including a Lenovo Bluetooth headset. The icon is seen in the upper right corner of the screen in the menu bar, with the date, time, battery life and wireless connection strength. The icon looks like two triangles on top of each other. If the icon is gray, click on it to enable Bluetooth.
Once you click the Bluetooth icon, a drop-down menu appears, with an option to Turn Bluetooth On. Once this is enabled, you will not need to make the computer discoverable. Make the headset discoverable, and the computer will discover it and pair. Repairing is often required, if the Bluetooth is disabled for any reason.
How to check if a PC has Bluetooth in Windows 10
Bluetooth is a wireless technology protocol for connecting a PC with external peripherals and devices. So it’s basically a protocol that enables you to connect a desktop or laptop with Bluetooth devices without any cables. Of course, you can still connect the devices with cables; but if your Windows 10 PC has Bluetooth support you can set up a wireless connection for them instead. If you upgraded a Windows 7 laptop or desktop to Windows 10, it might not support Bluetooth; and this is how you can check if that’s the case.
- First, press the Win key + X to open the Win X menu.
- Select Device Manager on that menu to open the window shown in the shot directly below.
- What you need to look for on that window is a Bluetooth Radios category. That should be listed somewhere nearer the top of the window.
- If you can’t find Bluetooth Radios, click Network adapters on the Device Manager window. Bluetooth Radios might be listed there instead.
- Alternatively, you can check for Bluetooth with the Control Panel. So select Control Panel on the Win + X menu to open it.
- Next, select Network and Sharing Center on the Control Panel.
- Now you should click Change adapter settings to open network connections below.
- You should find a Bluetooth Network Connection there. If you can’t find it listed there, then your laptop or desktop doesn’t have Bluetooth.
- Another way to check Bluetooth settings is to open the Settings app in Windows 10. Click the Start menu button and select Settings.
- Click Devices to open the window below.
- If you have Bluetooth, you should be able to select Bluetooth > More Bluetooth options.
Those who don’t have Bluetooth can still add it to their desktop or laptop with a Kinivo BTD-400 USB dongle. You can plug that into a USB slot on your desktop or laptop. Windows 10 and 8 should already include the required Broadcom Bluetooth drivers. However, you’ll need to manually download and install the drivers for earlier Windows platforms from manufacturer websites. Then you’ll be able to add devices by clicking a Bluetooth system tray icon.
So that’s how to check if your Windows PC has Bluetooth radio. Bluetooth devices are much more flexible, so it’s worth investing in a USB dongle.
How far away does a bluetooth computer work from a bluetooth printer
Bluetooth was the brainchild of the SIG (Special Interest Group). This SIG included Intel, Toshiba, Nokia, IBM, Compaq, Dell, Motorola, HP, Lucent, and Samsung to name a few. They all came together to set up a short frequency wireless technology for transferring data. Bluetooth is a communication pr…otocol. It is a like a language that devices use to wirelessly communicate between each other. It is in fact based on a Master/Slave operation format. Pico net is a term used to describe a network formed by one device and all other devices detected in its range. In single coverage are around 10 Pico nets can co-exist. A master can connect to more than one slave simultaneously. In reality, the master keeps switching between slaves. Bluetooth links two Pico nets to form a larger network. This works over a short range and can be used to establish connections between PDAs, mobile phones, laptops, digital cameras, printers, scanner, and many other electronic gadgets. Establishing a connection using Bluetooth is a complicated process. Initially, the device stays in a «Passive state», i.e. it is just in contact with the network, but not performing any activity. Next the connection establishment process begins with the inquiry process. «Inquiry» is a request sent by the master to all the devices found in its range. Whichever devices receive this inquiry send a response with their respective addresses. Now the master chooses one address and synchronizes with its access point. This process known as the «Paging technique» involves alignment of its clock and frequency with that of the access point. Next in line is the «Service Discovery» phase, wherein a link is established and the master device enters the access point using the Service Discovery Protocol. As a result of linking, a «Communication Channel» is to be created. Sometimes the access point may include a security mechanism and you may need to know the encryption key or in common terms the PIN. Once the PIN is sent and received and confirmed a communication is established. Finally the master and slave can use the communication channel to transfer data and information. Thus Bluetooth is neither a broadband nor a long distance networking technique. It is a Personal Area Networking technology that can be used in a number of important applications. First of all, Bluetooth technology uses the same frequency range as the Wi-Fi system. It only requires a careful coordination of the various frequencies with the perfect transmit and receive timings between various devices. Finally, the enhanced version of Bluetooth is expected to use Ultra-Wide Band frequencies that contributes increased data rate and improved signal strength. (MORE)
